Abstract

"DISPOSITIVO DE ATIVAçãO PARA DISPOSITIVO DE PROTEçãO DE OCUPANTE E MéTODO DE CONTROLE PARA O MESMO". O dispositivo de ativação (20) para um dispositivo de proteção de ocupante inclui um primeiro dispositivo de detecção de desaceleração (22) para detectar uma primeira desaceleração G na direção dianteira/traseira do veículo e um dispositivo de avaliação de ativação (37) para avaliar se a ativação do dispositivo de proteção de ocupante é necessária ou não comparando a primeira desaceleração G detectada pelo primeiro dispositivo de detecção de desaceleração (22) com um primeiro valor limite. O dispositivo ainda inclui um segundo dispositivo de detecção de desaceleração (24, 26) para detectar uma desaceleração LG, RG em uma posição no lado mais dianteiro do veículo que a posição que detecta a primeira desaceleração, um dispositivo de detecção de condição de colisão (35) para detectar uma condição de colisão de veículo baseada em um segundo valor limite pela desaceleração LG e RG e um primeiro dispositivo de mudança de limite (36) para mudar o primeiro valor limite de um dispositivo de avaliação de ativação (37) baseado no resultado detectado do dispositivo de detecção de condição de colisão (35)."ACTIVE DEVICE FOR OCCUPANT PROTECTION DEVICE AND CONTROL METHOD FOR THE SAME". The activation device (20) for an occupant protection device includes a first deceleration detection device (22) for detecting a first deceleration G in the front / rear direction of the vehicle and an activation evaluation device (37) for evaluating whether activation of the occupant protection device is required or not by comparing the first deceleration G detected by the first deceleration detection device (22) with a first limit value. The device further includes a second deceleration sensing device (24, 26) for detecting an LG, RG deceleration at a position on the front side of the vehicle than the position detecting the first deceleration, a collision condition sensing device ( 35) to detect a vehicle crash condition based on a second limit value by the LG and RG deceleration and a first limit change device (36) to change the first limit value of an activation evaluation device (37) based on detected result of the collision condition detection device (35).
